Medi-Ray is a Sentinel and MOA precept mod that allows either to periodically restore a percentage of its owner's health over 4 seconds.

1 4% 1
2 6% 2
3 8% 3
4 10% 4
5 12% 5


  • This ability has a 15 second cooldown
  • The total healing is based on your Warframe's maximum health, including mods. For example, with 300 maximum health, you will regenerate 36 health. With 740 health using Vitality12?cb=20190608095452 Vitality, you will regenerate 89 health.
  • Since the full heal takes four seconds to complete, this mod regenerates 1/4 of the listed percentage per second.
  • As the health restored is percentage-based, this mod will have a more noticeable effect on Warframes with higher health pools such as InarosInarosIcon272.png Inaros.


  • This mod, along with the other Executioner mods, are the second set mods to feature non-generic enemies on the mod card, the first being Vengeful Revenant12?cb=20190608095452 Vengeful Revenant.
